Pulsar: Absolutely loving Pulsar, the new XM/Sirius player for the Mac by Rogue Amoeba. I use it to listen to XM while at work, and also through my Apple TV at home (via Airfoil, another Rogue Amoeba product). Best of all I got Pulsar for free as an existing Rouge Amoeba product owner. See this page for details on that offer.
